Glenelg is an interesting area that NASA
researchers had previously imaged from above using the HiRise and
Mars Reconnaissance Orbiters. It looks like three different kinds
of rock meet there.

Here's a close up of some of the interesting looking rocks near
her, taken by her right NavCam, with the foothills of Mount
Sharpe in the distance: These

Here's how far she's come since leaving the area that she touched
down when reaching the Red Planet, Bradbury Landing. You can see
she's right on the edge of Glenelg:Over

And here's how weird the area looks from above:Taken
from above, researchers can see what they call a "triple
junction" of different rock types at the Glenelg site. Bradbury

At Glenelg, Curiosity still start her real science mission, which
could take several weeks. Curiosity will probably drive around
the area a little bit more to investigate the area and pick the
right rocks to test. She will dig and drill and scoop the Martian
dirt and test its chemistry to find out if it could have
supported life.

Just yesterday the science team announced that some of the rocks
in several places in Gale Crater indicate that there was
definitely large amounts of liquid water in the area
possibly up to hip-height deep. But water is just one part of
what's needed to make a planet habitable.
